• Adding the LLC
– Add only water if the mixture reduces in amount
by evaporation.
– If there is a mixture leak, add the LLC of the
same manufacturer and type in the same
mixture percentage.
– Never add any long-life coolant of different
manufacturer. Different brands may contain
different additive components, and the engine
may fail to perform as specified.
• When the LLC is mixed, do not employ any
radiator-cleaning agent. The LLC contains
anticorrosive agent. If mixed with the cleaning
agent, sludge may build up, adversely affecting the
engine parts.
• Service life of Kubota genuine long-life coolant is 2
years. Be sure to change the coolant every 2000
hours or every 2 years whichever comes faster.

higher boiling point is obtained by using a radiator-pressure
cap which permits the development of pressure within the
cooling system.

adversely affects the DPF performance.
Consult your local Kubota Dealer to clean the filter.
IMPORTANT :
• The DPF needs to be cleaned with a specific
cleaning device. Do not disassemble the DPF
for cleaning or try to clean it yourself. Consult
your local Kubota Dealer.
